SMOKERS PIPE.

' Specification of Letters Patent.

Application filed March 5, 1918. Serial No. 220,536.

To all whom it may concern:

Be it known that we, WILLIAM F. MoENKE, a citizen of the United States, and CARMINE A. SARLO, a subject of the King of Italy, residing at Sunrise, in the county of Platte and State of Wyoming, have invented certain new and useful Improvements in Smokers Pipes, of which the folowing is a specification.

This invention relates to smokers pipes and has as its primary object to provide a pipe which will enable one to obtain a cool smoke free from nicotin and the objectionable tobacco oils and which pipe will not be liable to become clogged because of saliva reaching the tobacco in the bowl of the pipe.

It is a further aim of the present invention to provide a smokers pipe possessing the features, and advantages above mentioned which pipe will be'simple in construction, may be readily and thoroughly cleaned whenever desired, and will not be liable to have its valves clogged eitherv by the tobacco or by saliva.

In the accompanying drawings Figure 1 is a view partly in side elevation .and partly in vertical longitudinal section illustrating the pipe embodying the present invention; v

F ig. 2 is a horizontal sectional View; Fig. 3 1s a detail longitudinal sectional arrangement of the saliva valve;

Fig. 4: is a horizontal sectional view illustrating the smoke and saliva ducts which are provided in the stem of the pipe;

- Fig. 5 is a detail longitudinal sectional view through the mouthpiece of the pipe.

- Asi usual, the pipe embodying the present invention includes a bowl indicatedLin general by the numeral 1 and having 111- tegral therewith a stern section 2 which may be made as shown in the drawings or suitably curved if desired and, of course, this stem section may be formed of any desired length, it being understood also that the in the manufacture of smokers pipes of this class. The-mouthpiece orbit of the pipewhich comprises there'rnainder of the stem, thereof is indicated in general by the numeral 3 and this mouthpiece or stem section is designed at its inner end in any suit- Patented se t. 24, 1918.

able manner for connection with the end of with a ferrule 4, as foreXample, of sheet metal, which is adapted to be frictionally fitted over the tapered end of the stem sec tion 2. It will be understood, however, that various other types of connection may ,be provided as, for example, a'threaded connection. Thestem of the pipe as a whole is provided witha smoke duct and also with a saliva duct and these ducts may be provided by forming small bores,v in any suitable manner, in'the stem sections or within such bores, we may find it desirable 'to arrange small metal tubes which will in themselves constitute the ducts. Thus in the instance of that embodiment of the invention, shown in the drawings, a smoke tube 5 and a saliva tube 6 are fitted in-bores formed in the mouthpiece or stem section 3 and in the illustrated structure the smoke duct or tube the tubes each being terminated atone end substantially at the bit end of the mouthpiece 3 and at the other endextending beyond the ferrule 4:, as indicated respectively by the numerals 7 and 8. Thus the tubes 5 and 6 project at their last mentioned ends within the ferrule 4 and are adapted to fit ings or ducts 9 and 10 respectively which are formed in and extend longitudinally of the stem section 2 and their forward ends communicate with the interior of the, bowl stem section 2 or, within such bores, small .into correspondingly formed alined openof the pipe. These ducts 9 and 1j0, -may as in the case of the ducts Sand 6, be produced I i by the mere formation of small bores in the tubes may be placed corresponding to the 7 'tubes 5 and 6. It will probably, however,

be found more desirable, to provide the ducts .9 and 10 merely by the, formation of I bores directly in the stem section 2, as illustrated inthe drawings, so that the-projecting ends 7 and8 of the tubes 5 and 6-may fit withinthe outer ended the said bores 9 and 10 when the ferruleet is fittedonto the outer end of the stem section ,egrne duct 9 at is forward end communlcates directly with the bottom of the tobaccochamber of smoke from the burning tobacco ,willbe drawn into the end of thesmokeldu'ct 9, and

through this duct and through the duct 5 to the smokers mouth. In the use of the ordinary smoking pipe annoyance is caused through saliva flowing through the smoke duct to the tobacco chamber of the bowl and in the instance of our invention this is effectually prevented through the provision of a small valve for normally closing the outlet end of the duct To accommodate this valve, the end of the said duct 5 at the bit end of the stem section 3, is interiorly flared to provide a valve seat 12 and the valve, which is indicated by the numeral 13, is in the nature of a small cone which normally rest within the seat 12 so as to, as above stated, close the smoke duct. A very small coil spring 14 is seated at one end against a shoulder 1 1 formed in the duct 5 and at its other end is straightened as indicated by the numeral 15 and has its straightened portion extended back through the coils and connected to the valve 12 as at 16. It will now be understood that normally the pull exerted by the spring 13 serves to hold the valve to its seat and consequently saliva cannot flow into the smoke duct and to the tobacco chamber of the pipe. However, the free drawing of the smoke from the pipe is not in any way interfered with for as soon as smoke is drawn in the act of smoking the valve 13 will be moved away from its seat, being automatically immed ately returned when the suction or draft is removed. In pulling upon a pipe air is supplied to the burning tobacco from the bottom of the tobacco chamber as well as from the top and whereas in the ordinary pi e air is puffed through the smoke duct to the burning tobacco in the bowl, this cannot be done in the instance of the pipe embodying our invention as the valve 12 closes the smoke duct. However, air is supplied, in the act of puffing of the pipe, through the aliva duct 6 but this is accomplished without any possibility of saliva reaching the burning tobacco in the bowl, in the manner which will now be described.

While the duct9 leads directly to the bottom of the tobacco chamber of the bowl 1, the duct 10 extends beneath the bottom of the said chamber and into the front of the bowl and thence in an upward direction, as indicated by the numeral 17 co1nmunicating at its end with a valve casing which is indicated in general by the numeral 18 and which is "seated in a suitable recess or pocket 19 formed in the inner surface of the wall of the tobacco chamber. The valve casing 18 is made, for example, from metal of a noncorrosive kind and may be secured in place in the recess or pocket 19 in any suitable manner as, for example, by small screws '20 which are fitted through openings in the wall of the tobacco chamber and threaded "into the casing 18, as clearly shown in Fig. 2

of the drawings. The casing 18 is formed interiorly with a valve seat 21 and with an inlet duct 22 which communicates with the said seat and also communicates with the branch 17 of the duct 10. A. conical valve 23 is arranged within the valve casing and normally is held to the seat 21 by means of a coiled spring 24 which seats at one end against a shoulder 2& formed in the duct 22 and is straightened at its other end and led back through the coils and connected to the valve. The casing is provided with an outlet opening 25 which communicates with the interior of the tobacco chamber in the bowl 1 and it'is also preferable that the casing be formed in its top with an opening 26 through which the valve 23 maybe introduced and removed. It will now be evident that when, in the act of smoking the pipe, air is puffed through the saliva duct comprising the sections 6 and 10, the valve 23 will be momentarily lifted from its seat thus pe-rn'ii'tting theair to pass into the valve casing and through the opening 25 into the burning tobacco in the bowl. As the saliva duct 10 is given an upward turn informing the branch 17, saliva will not be discharged from this duct into the tobacco chamber of the bowl, but instead will merely accumulate inthe lower portion of the duct and will also accumulate in a small pocket 27 formed ina' saliva plug '28 which is removably, frictionally fitted or threaded into the underside of the bowl at the point of junction of the stem section therewith.

From the foregoing description of the invention, it will be understood that in the use of the pipe embodying the same, air will be supplied to the burning tobacco in practically the same manner as in the instance of an ordinary pipe and thus the same draft is provided as ordinarily and yet there is no likelihood of saliva flowing through the smoke duct and reaching the burning to-' bacco in the bowl. It will also be evident from the foregoing that the valves are so located that they may be readily cleaned or repaired and their location is, furthermore, such as'to prevent any possibility of clogging of either the smoke orsaliva ducts, noris there any likelihood of the valves themselves being clogged or held away from'their seats through particles of tobacco as the tobacco will never reach the valve 13 and the opening 25 is so small that it cannot enter into the valve casing 18 through thisopen- Having thus described our invention what is claimed as new 1s:

1. In a smokers plpe, a bowl, a stem, the

stem having a smoke duct leading to the bowl and having a saliva and air duct also leading to the bowl, a check valve in the smoke duct arranged to open with "draft from the bowl, and a check valve in the saliva and air duct arranged to open with draft to the bowl.

2. In a smokers pipe, a bowl, a stem, the stem having a smoke duct leading to the bowl and having a saliva and air duct also leading to the bowl, a check valve within the smoke duct at the bit end of the stem arranged to open with draft from the bowl, and a check valve within the saliva and air duct approximately at the point of communication of the said duct with the bowl and arranged to open with draft to the bowl.

3. In a smokers pipe, a bowl, a stem, the stem having a duct leading from the bit end thereof toward the said bowl and provided with an upwardly extending branch opening at its upper end through the wall of the tobacco chamber of the bowl, and a check valve arranged within the duct to open with draft to the bowl. 7

4. In a smokers pipe, a bowl, a stem, a valve casing arranged within the wall of the tobacco chamber of the bowl and having an outlet communicating with the interior of the said chamber, the said casing being provided with an inlet, the stem having a duct leading therethrough and communicating i at one end with the inlet to the valve casing and at its other end opening through the bit end of the stem, and a check valve arranged within said casing between the inlet and outlet.

5. In a smokers pipe, a bowl, a stem, a

valve casing arranged within the wall of the tobacco chamber of the bowl and having a passage communicating with the interior of the said chamber, the casing being provided with an inlet, the stem of the pipe having a formed in its under side with an opening communicating with the first-mentioned duct, and a removable plug closing said opening.

In testimony whereof we affix our signatures.
